What is the reversing radar?

Click:    date:1970-01-01 08:01:00

Reversing radar (PDC, Parking Distance Control) the full name of "reversing radar", also called "parking auxiliary device", is a safe auxiliary device of car parking or reversing, ultrasonic sensors (commonly known as the probe), the controller and display (or buzzer) parts. When reversing, helps the driver to "see" the rearview mirror, the invisible, to sound or more display around the obstacles of this pilot intuitive, lifting the driver parking, reversing andstart the vehicle around the problems caused by the visitand help the driver, to remove the dead ends and vision blurred vision defects, improve driving safety.

 

 

Reversing radar also has some blind spots, including obstacle is too low (below the probe center 10~15cm the following obstacles), obstacle meticulous (e.g. isolation pile,cable-stayed cable) and ditch.

Domestic brands: the Ultralisk, rail car, hit four, billion, blue thunder, an extremely star, Haodi, Pathfinder God, road signs, solid, baostep, Linfor, two Lang God, World Expo,the first German, state, black hawk, an etc..

Reversing radar working principle

The working principle of PDC system is usually radar detector arranged in the rear bumper and front and rear bumper car, used to detect the obstacles before, help the driver to "see" the obstacle before and after the party, or stop and its distance from the vehicle, the device not onlyconvenient parking also can protect the body againstscratch.

PDC is based on ultrasonic sensors to detect obstaclesfrom recent distance, and issued the siren to warn the driver. While controlling the siren sound is usually divided into two phases, when the distance of the vehicle reaches astart to detect the distance, the siren sound began to singa high frequency of the sirens, and when the car goes to acloser, then the siren to continuous siren, to inform the driver. The advantage of PDC is that the driver can obtain the obstacle information with the hearing, or the car from the glass. The PDC system is mainly to help stop, so as to meet or exceed a speed system function will be closed.

Choose to pay attention to aspects of reversing radar:

1, quality: reversing radar as an automotive supplies, the most important is to see its quality is excellent, quality products to provide a service better, longer aftercommitment.

2, functional aspects: distinguish from the aspect of function, reversing radar can be divided into the LCKdisplay, voice prompt alarm distance, bearing, voice prompt, automatic detection probe, a full-featured reversing radar should have these functions.

3, performance: performance mainly from the detection range, accuracy, stability and capture the target speeddisplay to verify. The detection range of at least 0.4 meters to 1.5 meters; precision mainly depends on two aspects,first look at the display resolution, generally 10 cm, good can reach 1 cm, then see detection error, namely thedisplay error distance and the actual distance between thedetecting error, good products less than 3 cm; display stability in disorder compound reflector is not good, can capture and stable showing obstacle distance; capture target speed reflects the ability to capture the reversing radar for moving objects. Reversing radar performance requirement is: the measured accurately, the measuredsteady, Fan Weikuan and capture speed.

4, the appearance of Technology: as the inside and outside decoration of automobile, the overall structure,color coordination and car.

After reversing radar

After reversing radar is a safety auxiliary device for automobile parking or reversing, ultrasonic sensors(commonly known as the probe), the controller and display(or buzzer) parts. Can use sound or a more shows around the obstacles of this pilot intuitive, lifting the driver parking,reversing and start the vehicle around the problems caused by the visit and help the driver to remove the vision,dead and blurred vision defects, improve driving safety.

After reversing radar probe is arranged in the rear bumper,probe to about a 45 degree angle radiation, above and below the search target. The biggest advantage is that itcan explore to those below the bumper and the driver from the obstacle, the rear window to see and alarm, such asTan, squat playing in the car after the children.

Gear into reverse gear hanging rod, reversing radarautomatic start work, when the probe to detect rear objectwhen the buzzer alarm, when the vehicle to reverse, alarmsound frequency will gradually accelerated, and finally into the ringing tone.
